My '73 26' Argosy battery doesn't seem to be charging. It's been plugged in for weeks but the battery has gone out from running the lights and heater fan occasionally. Is the battery suppose to charge when it's plugged in? If so, can someone recommend some steps to take to see if it's charging and how to repair it?

If you have the original Univolt converter it may have failed. Even if it didn't, it's time to upgrade.
Is there water in the battery?
Have you checked the fuses?
What is the voltage at the battery when you are plugged in?
Is there 120 volt AC power to the converter?
Have you checked the connections at the battery?

It is the original univolt. Whats the recommended upgrade?
I have a good battery. I haven't pulled the univolt yet to see if everything is hooked up properly, there is a water line blocking me from removing it. It's just not a project I have had as a priority to tackle yet... I guess it's time now.

I installed a Progressive Dynamics 9245 in my '74 Argosy 26' in 2010. It has worked flawlessly since.
Even without a battery it powers everything.
I usually remove the battery when the coach is stored. Use it for other things. Just tape off the positive lead and plug the coach in. That way I have lights and heat if I need it.
I did install a new fuse block as well.
